No. 741,776 Int. Cl. B61d 17/12; E04d N28 US. Cl. 52-46 4 ClaimsABSTRACT OF THE DISCLOSURE A roof construction for a vehicle havinglongitudinal sheathing members supported on transversely disposedcarlins having aligned notches. The sheathing members are deformed alongtheir edges to constitute stringer portions which are received in thealigned notches. The deformed stringer portion of one sheathing memberis overlapped by an edge portion of a next adjacent sheathing member.

One type of roof construction which has previously been used for suchpurposes includes longitudinally spaced carlins connected at their endsby through-running Z-shaped beam members to enable securement of theroof to the side walls of the vehicles. A longitudinally running roofcovering is afl'ixed to the top surfaces of the carlins. In additionlongitudinally extending stringer members are secured to the downwardlyextending web portions of the transversely disposed carlins. Adisadvantage of such construction is that the stringers arediscontinuous and are not through-running. Consequently joints arerequired at the ends of each stringer portion thereby accounting for agreat multiplicity of joints.

It is an object of this invention therefore to provide an improved roofconstruction which avoids one or more of the disadvantages of the priorart constructions and which eliminates labor in putting the sametogether.

It is another object of this invention to provide a roof constructionwhich is less costly and which eliminates the possibility of leaks as aresult of cutting down on the number of joints required.

For a better understanding of the present invention together with otherand further objects thereof reference is had to the followingdescription taken in connection with the accompanying drawings and itsscope will be pointed out in the appended claims.

In the drawings FIG. 1 is a side elevational view of a portion of anenclosed railway vehicle embodying the invention;

FIG. 2 is a partial enlarged section taken along the line 22 of the FIG.1;

FIG. 3 is a sectional view taken along the lines 33 of FIG. 2;

FIG. 4 is a sectional view similar to that shown in FIG. 2 butillustrating a modified form of the invention;

FIG. 5 is a sectional view taken along the lines 55 of FIG. 3illustrating the carlin.

A vehicle 10, in the present instance, an enclosed railway car adaptedfor suburban passenger usage, has a roof 11, side wall 12 and a floor13.

The roof assembly includes longitudinally spaced carlins 15 connected attheir side ends by Z-shaped roof sill members 16. The side wall includesvertical posts 17, outer covering skin 18 and an inner top plate 19capped at the upper end by the aforementioned Z sill member 16.

As seen in FIG. 2 the ends of the carlins are supported on the topsurface 21 of the roof sill member 16 and are secured in place by gussetmembers 23. The latter gusset includes a horizontally disposed flange 24which rests on the top surface 21 of the sill member and in "iceaddition a side flange 25 engages its vertical web. The carlins 15 mayalso be of Z section and support a plurality of generally flat sheathingmembers 26, first, 27, second and 28, third on their upper flangesurfaces.

As seen in FIG. 2 the carlins 15 include a plurality of cut-outs 29,spaced along the upper peripheral edged surface of the top flange of thecarlins. Adjacently disposed carlins 15 along the longitudinal axis ofroof include like spaced cut-outs 29, 30. It is noted in addition thatthe upper edge of the longitudinal skin sheathing member 26 includes ahat shaped deformation in cross section, 31, disposed along its upperlongitudinal edge. The like spaced cut-outs 29 of adjacently spacedcarlins receive the inverted hat deformation 31 of the firstlongitudinal sheathing member 26. The second sheathing member 27 spacedabove sheathing member 26 includes a lower edge portion 32 whichoverlaps the longitudinal stringer deformation 31 of sheathing member26. The portions may be suitably welded as at 33. When so joinedtogether the hat deformation 31 of the first sheathing member 26 plusthe edge overlapping portion 32 of the second sheathing member 27 formsa box section in cross section which has great torsional strength.

The second sheathing member 27 likewise includes a longitudinaldeformation along its upper edge as at 34 which is likewise of invertedhat section. The latter hat 34 cooperates and is received in the alignedcut-outs 30 of adjacently spaced carlins. In the same manner the nextadjacent sheathing member 28 overlaps sheathing member 27 at its hatsection 34 and is likewise joined to form a longitudinal stringer of boxshape in cross section. In order to compensate for the loss of materialin the carlins due to the cut-outs 29, 30 bracket members 37 of angleconstruction are affixed to the web of the carlins at the base of thecut-outs. The angle member includes a longitudinally extending flange 38which supports the under lower surface of the hat deformation 29.

A modification of the roof structure of FIG. 1 and embodying thisinvention is shown in FIGS. 4 and 5. The modified form of the inventionincludes composite carlin members extending transversely of the vehiclebetween the side walls 12 of the vehicle. Each carlin 45 includes alower arcuate Z-shaped member 46 which extends completely across thewidth of the car and is supported on its ends by the aforementioned roofsill members 16. A plurality of arcuate angle members 47 are disposed inprojecting relationship above the top edge 48 of the lower carlin member46. Each angle member 47 includes a downwardly depending flange 49 whichis secured to the vertical flange 50 of carlin member 46. The anglemembers 47 include in addition top horizontally extending flanges 51which are arcuately curved and support sheathing members 26, 27, 28 asarranged in the previously described FIG. 2. Adjacent spaced uppercarlin angle members 47 as seen in FIG. 4 include edge portions 53, 54which together with the top surface or flange 48 of carlin member 46define a cut-out 57. The cut-outs 57 are like spaced as to adjacentlongitudinally disposed carlins 45. These cut-outs serve to receive theinverted hat portions 31, 34 of adjacently disposed sheathing members.As previously indicated the lower longitudinal edge portion 32 ofintermediate sheathing member 27 is shown in overlapping engagement andafiixed to the marginal edges of hat deformation 31 of lower sheathingmember 26. A like construction is shown to exist between upper sheathingmember 28 relative to intermediate sheathing member 27. From the abovedesscn'bed construction it is seen that discontinuity of thelongitudinal stringers at each transverse carlin member is eliminated.This construction thereby saves the labor in assembling the variousmembers together. Moreover costs are in addition saved by theelimination of leaks as a result of cutting down on the number ofjoints.

While there have been described what at present are considered to be thepreferred embodiments of this invention it will be obvious to thoseskilled in the art that various changes and modifications may be madetherein.

1. A roof construction for a vehicle having side frames and comprisingin combination, a plurality of carlins spaced in adjacent relationshipalong the length of said car, said carlins extending transversely ofsaid car and mounted for support by said side frames, each of saidplurality of carlins having a top edge defining an opening therein,first and second sheathing means supported on the top edges ofadjacently spaced carlins, said first sheathing means including alongitudinally extending deformed portion received into said openings ofsaid adjacently spaced carlins, and said second sheathing meansincluding an edge portion overlapping said deformed portion of saidfirst sheathing member and secured thereto.
